JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
• Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e., do
not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
270 WHAT TO DO IN EMERGENCIES

1. Attach one jumper cable to the positive terminal ofbooster battery and the other end of the same cable to
the positive terminal of the discharged battery.
NOTE: Do not jump off fuses. Only jump directly off
positive post.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.

2. Connect one end of the other jumper cable to negative(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of
the vehicle with the discharged battery. Make sure a
good connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
• During cold weather when temperatures are below
freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump starting because
the battery could rupture or explode. The battery
temperature must be brought up above freezing
point before attempting to jump start. 3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do
not lean over the battery when making connection.
The negative connection must provide good electrical
conductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start, cables must be disconnected in the following order:
• Disconnect the negative cable at the engine ground.
• Disconnect the negative cable at the negative post on
booster battery.
• Disconnect the cable from the positive post of both
batteries.
